Eye Doctor option
Eye doctor is a set of tools for analyzing signals in high bit rate serial data systems which generally
employ equalization. Eye Doctor consists of two features that are orderable separately or bundled
in one package. The two features are:
Virtual Probing – this feature simulates a signal at any point in a network using measurements at
any other point in the same network.
Equalized Receiver Emulation – This feature implements a simulated receiver including
equalization (DFE and FFE), clock recovery and detection. Equalized receiver emulation allows
signals to be viewed as they would appear inside a receiver chip.
Eye Doctor is explained in detail in a separate manual.
Math Tools (standard)
• Display up to eight math function traces (F1 to F8). The easy-to-use graphical interface
simplifies setup of up to two operations on each function trace. Function traces can be
chained together to perform math-on-math.
• Parameter math -- add, subtract, multiply, or divide two different parameters.
• Histograms expanded with 19 histogram parameters and up to 2 billion events.
• Trend (datalog) of up to 1 million events
• Track graphs of any measurement parameter.
• FFT capability includes: power averaging, power density, real and imaginary components,
frequency domain parameters, and FFT on up to 25 Mpts.
• Narrow-band power measurements
• Auto-correlation function
• Sparse function
• Cubic and quadratic interpolation function
• User-definable parameter measurements and math functions, using VBScripting with MS
